To ZZ fio/'wm if 'may concern.:

Be it known that L lli'innnizir E. Tmrrnn- 'roN, a citizen of the. United fritates, and resi-- dent ot' l'osiindnle7 county of Suli'olli. State 5' of Masaehneetie, have inveiuied. an 11nprovenieut. in 'ieain Traps, of which the following description, inaeonneetion 'with .20 the valve. mechanism which can he readily adjusted so that` the. valves will operate when the water level in thel trap reaches any desired poinhzfind which will he accurate `in its operation under all adjustments.

' simplifying the structure.

- The float arm 2G is made hollow as shown in Figs. 4 and 5 and the rock shaft 27 is also provided with a duct 42 extending longitudinalily thereof and communicating with the interior of the tubular arm 26. The duct 42'is open to the atmosphere. If the float should leak and water could accumulate therein then when the float is at the upper limit of its movement, such water will flow' down the hollow ioat arm 26 and will be discharged through the duct 42. It will, therefore, be seen that I have provided' a construction by which the float will be automatically drained.

It will be observed that the valve structure is compact and is made as a unit which is removably secured to the head i", thus Furthermore by plat-zing.;` the valves on the head 7 it is possible to use a standard valve construction and a standard head 7 for casings of different sizes and shapes, it only being necessary to secure-the head 7 with its valve structure to the casing whatever its size or shape.

In Figs. l and 3 I have illustrated a construction where the casing, indicated at l, is cylindrical in shape yand provided with bumped ends 43. In this embodiment of the invention the head 7 with the valves thereon and the float associated therewith, is secured` to a neck 6a, which is in turn secured to one of the ends 42 of the casing la. Ihe inletl pipe is indicated at 2 and the delivery pipe at 4a, they being arranged to communicate with the bottom of the casing l. They arc provided with the check valves 3 and 5 as in the en'rbodiment above described.

.ln the enibodin'ient shown in Figs. and 3 l have employed the valves 8 and 9 as pilot valves, which in turn control larger steam and vent valves, this being a desirable construction where the casing la is of extremely large size so that a considerable valve opening is required to admit the steam to the casing 6r to vent the latter.

In said ei-nbodiment 45 indicates the steam pipe leading to a source of steam .supply and communicating with the easing la through a connection 4G. This pipe has a dilerential valve47 therein which normally closes the steam pipe 45 but which is opened when the pilot valve 8 is opened. The valve 47 has a valve member 48 seating on a valve seat 49, ,said valve being normally held closed .by the steam pressure in ther pipe The pipe 46 leading into the casing lLL Ais l below thevalve seat 49. In the lower end of the valve 47 is a cylinder 5() in which op crates la piston 51 having a'pin 52 extendingtherefrom whici is adapted to engage the valve 48 and lift it ofi' its seat. The space 53 beneath the piston 5l is connected to the port 13' of the valve 8, by means olf a suitable pipe" 54. The port 14 ot' said `valve 1s connected with the steam pipe 45 bv a pipe 55. AVVli'en, therefore, the valve 8 1s opened steam Afrom the supply pipe 45 will be admitted to the cylinder 53 thereby raising the piston 5l and opening the valve 48. This will allow steam in large quantities to enter the casing ll'throngh the connection 46. i

The casing la has a vent pipe 57 communicating therewith which is closed by a valve indicated at 58. This valve is no1-mall y' -held yopenloy a spring 59 acting on the valve stem 60. 6l is a housing containing adiaphragm connected to the valve stem 60.

62 is a steam pipey communicating with the vpipe 54 so that when the pilot valve 8 is open the diaphragm 6l will be subjected to steam pressure thus closing the valve 58, The pilot vent valve 9 has a port 13 leading to the atmosphere andthe port 14 eommunicating by -a pipe 63 with the pipe' 62 so that when the vent valve is opened the diaphragm chamber will be vented. When this condition exists the spring 59 will open the valve 58. v

In this embodiment of the invention when the steam pilot valve 8 is closed and the vent valve 9 is open, the main steam valve 4i" will also be closed by the steam pressure and the main vent valve 58 will be held open` by the spring 59, thus allowing thecasing l to be ilhledwith water. When the casing is full and the cradle 32 is operated to reverse the valves 8 and 9, then steam will be admitted to the chamber 53 thereby opening the steamyalve 48 and will also be admitted to the diaphragm chamber thus closing the vent valve 58. At the same time the vent valve 9 is closed. Steam will thus be admitted to the casing la andthe water will be forced out of said casing into some other receptacle, such for instance as a steam boiler. When 'the casing la is empty the cradle will be reversed thus opening the vent valve 9 and closing the steam valve an-'l this operation will vent not only the chamber 53 thus allowing.,r the steam valve. 48 to close .but will also vent the diaphragm chamber 6l thus allowing the vent valve 58 to close.
